PV=46.9+(.105*NETAPP)+(.635*Q2GDP)+(5.22*TERMINC)-(2.76*POLARIZATION)īelow is an interactive model that we can explore, plugging in your own variables. POLARIZATION – takes on the value of 1 when there is a first term incumbent running or in open-seat elections when the incumbent president has a net approval rating > 0 it takes on a value of -1 when there is not a first-term incumbent and the incumbent president has a net approval rating 0, = -1 no first time incumbent and incumbent approval “This suggests that the growing partisan polarization is resulting in a decreased advantage for candidates favored by election fundamentals including first term incumbents.: – Abramowitz “This basic model has correctly predicted the winner of the popular vote in the last 5 presidential elections with an average error of 2 percentage points.” -Abramowitzīecause in the last 4 Presidential elections, the basic model overestimated the winning candidate’s share of the votes. TERM1INC stands for the presence or absence of an first term incumbent in the race.

Q2GDP stands for the annualized growth rate of real GDP in the second quarter of the election year, and.

NETAPP stands for the incumbent president’s net approval rating (approval-disapproval) in final Gallup poll in June.

PV stands for the predictive share of the majority party vote of the incumbent president.

One of the most interesting models in Presidential elections is Alan Abramowitz’s Time for Change Model based on what is now referred to as the campaign fundamentals. We argue about models, back test them, refine them, and then use them to predict outcomes. Often models are used to present a hypothesis in a clear manner. There are many reasons for developing and using models.
